CHAIN FASTENER.

Application fileiiseptember 9, 1926. Serial Na-134,528.

This invention relates to a'fastener device illustrated in the accompanylng drawlngs and specifically claims.

In describing myinvention in detail, refpointed out in the appended erence will be had to the accompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:- 4

Figure 1 is a view showing the invention used to hold an anti-skid cha n on a tire.

Figure 2 is an elevation of the device itself.

Figure 3 is a similar view but showing the parts in open position.

Figure 4 is a top lan view.

. Figure 5 is a longitudinal sectional .view. Figure ,6 is a front end view, with parts in section. 1 \4 v Figure'7 isa transverse sectional view. In these views, '1 indicates a cylinder which is formed with the'openings2 in its 1 piston in adjusted sides and said cylinder has one of its end pieces 3 fastened therein by the bolts 4.

The other end (piece may be formed with the sides. The en piece 3 is provided with an opening 5 which has a portion of its wall beveled to form atooth 6. A piston 7 is arranged in the cylinder and its rod 8 passes through the opening 5 and has teeth 9 thereon for engaging the tooth 6 to hold the coiled spring 10 is arranged in the cylinder and tends to hold the pistona'gainst the rear end of the cylinder. The teeth, are so formed that the spring will move the piston toward the rear end of the cylinder, the teeth 9 sliding over the tooth 6, but movement in an opposite direction will be'prevented by the en agement of the teeth, unless the piston r0 1s moved against the other end of the opening 6 which will move the teeth thereonout of engagement .with the tooth 6. Then the parts can be moved outwardly against the action of the vspring.

osition in the cylinder.

A latch member 11 has its hooked end pivotallyand movably connected with; the outer end of the rod 8 by means ofthe pin and slot connection 12, and said latch member is held-in latching position by means of a snap hook 13 carried by the c linder and engaging the member tohold 1t adjacent the cylinder, as shown in Figures -1, 2 and 5. A

forked spring 14; is fastened to the outer end of the rod 8 and has its forked part engaging the member-ll, when said member is in closed position and this spring 14 presses the rod 8 against the tooth 6.

' A split loop member 15 is swiveledin the rear end of'the cylinder.

As shown in Figure 1, the member 15 is placed in engagement with the end link of one of the side chains of the anti-skid device A and the latch member 11 is passed through the opposite end link of the side chain and then the latch member-is moved to closed' position and placed in engagement withthe snap book 13, which looks. it in closed portion. The spring 14 will then pressthe piston rod against the tooth 6 so that the rod cannot move outwardly but it is permitted to more inwardly under theaction of the spring against the piston. Thus slack in the side chain or any other chain or flexible member to which the device is connected, will be automatically taken up by the'device. I

I It is thought from the foregoing description that the advantages'and novel features of my invention. will bereadily apparent.

I desire it to be understoo make changes in the construction and in the combination and arrangement of the several parts, providedwthat such changes fall within the scolpe of the appended claims.

What claim is 1. A (lGVlCG'OfHthG class described comprising a cylinder, a piston therein, a piston rod having teeth thereon, one end of the that I may piston having 'a hole therein through which the rod passes, a part of the wall of the hole 7 being formed witha tooth to engage the inga cylinder, a piston therein, a piston rod having teeth thereon, one end of the piston having'a hole therein through which the rod passes, a part of the wall of the hole being formed. with a tooth to engage the teeth of'the rod, a latchmember fastened to the outer end of the rod and means on the cylinder for holding the latch member in closed position.

3. A device of the class described comprising a cylinder, a piston therein, a piston rod having teeth thereon, one end of the piston having a hole therein through which the rod passes, a part of the wall ofthe hole being formed with a tooth to engage the teeth of the rod, a latch member fastened to the outer end of the rod, means on the cylinder for holding the latch member in closed position and a spring on the rod and engaging the latch member, when the same is in closed position, for holding the toothed part of the rod against the tooth at the'end of the cylinder.

4. A device of the class described comprising a cylinder, a. piston therein, a. piston rod having teeth thereon, one end of the cylinder having a hole therein through'which the rod passes, a part of the wall of the hole being formed with a tooth to engage the teeth of the rod, a spring for holding the piston in retracted position and a latch member fas: tened to the outer end of the rod.
